SAN DIEGO Sure signs that you're a San Diego vacation veteran: The employees at Kono's Surf Club Cafe in Pacific Beach know your order by heart (breakfast burrito No. 3, extra bacon). The hostess at Miguel's Cocina on Coronado Island puts your name on the waiting list as soon as you enter the courtyard. Your neighbors at the Beach Cottages or Carlsbad Inn are on your Christmas-card list.
